#2 Drew McIntyre
Drew McIntyre is currently flying high in WWE as he will be fighting Roman Reigns at the Grandest Stage of Them All. McIntyre has been the focal point of RAW in the last few weeks. The Scottish Psychopath defeated two members of the Shield. Interestingly, Seth Rollins was one of two members of the Hounds of Justice. Though there was a distraction from Brock Lesnar, McIntyre managed to pin Rollins.
There is no denying that Vince McMahon's billion dollar company is building McIntyre as the future Universal Champion. The Scottish Psychopath has become a dominant superstar of the red brand, and he is undoubtedly the biggest heel of the flagship show. With his current momentum, he has a bright possibility to overpower Roman Reigns at the Showcase of Immortals.
Rollins and McIntyre are not new rivals as they locked horns in the past. Though the two men had some bouts in the past, they never had a lengthy feud.
